The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.

Kirishima (新燃岳 in Japanese), one of Japan's most active volcanoes. It is actually a group of 18 young, small stratovolcanoes north of Kagoshima Bay: Takachihonomine, Nakadake, Ohatayama, Karakunidake, Tairoike, Ohachi, and Shinmoedake are the principal vents.
Historic eruptions have been recorded since 742 and there are more than 60 recorded eruptions, mainly from Ohachi and Shinmoedake, with the exception of a small lava flow from Iwoyama in 1768. Relatively large eruptions occurred in 788, 1235, 1716-17 and 1768, and in 2011.
A violent eruption started at Kirishima on January 26, 2011, the largest one for more than 50 years.
